White Paper

Overview

When Cisco Unity™ first become available on the Cisco ICS 7750 Integrated Communications System, it was installed as a Voice-mail-only system and did not provide unified messaging. If customers are not planning to migrating to unified messaging later, Cisco Unity should be installed in its own Windows 2000 Domain and Exchange Organization and remain separate from customers' existing environments. If however, the customer does plan to migrate to unified messaging in the foreseeable future, Cisco Unity should be installed into the customers' existing Windows 2000 Domain as a member server.

This document describes the requirements and provides step by step instructions for installing Cisco Unity Voice Mail for the Cisco ICS 7750 into a customer's existing Windows 2000 Domain. Objectives of this paper:

•Describe the setup of the customer's existing environment

•Describe the process of installing Cisco Unity into this existing environment

Overview of the Cisco ICS 7750

The Cisco Integrated Communications System (ICS) 7750 brings the benefits of converged IP services to midmarket businesses and enterprise branch offices. The Cisco ICS 7750 is a versatile IP telephony and services solution that helps businesses harness the power of the Internet through converged applications enabling them to anticipate and respond to customer needs more efficiently. Call processing, voice applications and multiservice IP routing are integrated within the system chassis to deliver true convergence while enhancing system manageability. The modular system architecture enables expansion of call processing, routing capacity, and IP services to deliver system availability and scalability. The Cisco ICS 7750 gives customers the flexibility to choose the optimal configuration for their business environment, and allows them to increase profitability through improved customer interactions.

Overview of the Organization

For this example the customer has an existing Windows 2000 Domain Controller and is also running Doman Name System (DNS) on this HP server. The overall organizational landscape might look something like this:

•The customer already has a Domain Controller (Cisco-tmeserver) with the global catalog since it was the first domain controller in the Forest. The customer also has DNS configured on this server for name resolution. The customer does not have Exchange in its environment at all.

•The Cisco Unity Systems Processing Engine (SPE) can be installed as either another Domain Controller or as a Member Server in the existing domain (Cisco.com). Installing the Cisco Unity SPE as a member server is preferred. Both methods will be detailed.

•A new Exchange Organization (Cisco) will be created on the Cisco Unity SPE as the first Exchange server in the Forest.

Installing ICS Unity into an Existing Windows 2000 Environment

After installing the Cisco SPE 310 blade with the Cisco ICS core software loaded into the Cisco ICS 7750 chassis, the first thing we want to do is to join the customer's existing domain.

Note: Make sure ICSConfig reflects the customer's DNS Server IP as the default.

Step 4. Change the Computer Name of the Unity SPE by right-mouse-clicking on the My Computer icon on the desktop, selecting Properties, selecting the Network Identification tab, and then clicking Properties there to change the Full computer name to "CiscoVM1".

Caution: If the Cisco Unity server will be the only server in the domain, you must install Active Directory. However, because Active Directory is a very processor and memory-intensive application, if you are adding the Cisco Unity server to an existing domain, we strongly recommend that you do NOT also install Active Directory on the Cisco Unity server. Instead install it as a member server in the existing domain.

Step 5. To add the Unity SPE as a member server to the existing domain continue with the following steps. If you really want to configure it as another Domain Controller (with Active Directory)—which is NOT recommended, skip to Step 15.

Note: To add the Cisco Unity SPE server to an existing domain without making it an additional domain controller in that domain, do the following:

•In the Summary screen, verify the information is correct before proceeding.

•Click Finish when you are informed that the Unity SPE has joined the customer's domain and has been assigned to the site "Default-First-Site-Name" or whatever the customer has specified as their Site Name.

Step 16. After rebooting the Unity SPE, logon to the domain as the administrator.

Step 17. On the Unity SPE, run the Active Directory Sites and Services utility and verify that the Unity SPE (CiscoVM1) has been added as another server to the Default-First-Site-Name.

Step 18. On the customer's Domain Controller, open DNS and verify CiscoVM1 server has an entry in the Forward Lookup Zone.

WARNING: You will need to run the AdSchemaSetup utility from the customer's Domain Controller that is also is configured as the Global Catalog, NOT from the Unity SPE.

Step 28. Execute the AdSchemaSetup utility on the Customer's DCGC

Step 29. Install Unity on the Unity SPE.

Step 30. Perform Integration with CallManager and test.

Obtaining Technical Assistance

Cisco provides Cisco.com as a starting point for all technical assistance. Customers and partners can obtain documentation, troubleshooting tips, and sample configurations from online tools by using the Cisco Technical Assistance Center (TAC) Web Site. Cisco.com registered users have complete access to the technical support resources on the Cisco TAC Web Site.

Cisco.com

Cisco.com is the foundation of a suite of interactive, networked services that provides immediate, open access to Cisco information, networking solutions, services, programs, and resources at any time, from anywhere in the world.

Cisco.com is a highly integrated Internet application and a powerful, easy-to-use tool that provides a broad range of features and services to help you to:

You can self-register on Cisco.com to obtain customized information and service. To access Cisco.com, go to the following URL:

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Inquiries to Cisco TAC are categorized according to the urgency of the issue:

•Priority level 2 (P2)~Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

•Priority level 1 (P1)~Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:

http://www.cisco.com/register/

If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:
